I've been using my Nexus 7 2013 LTE for almost a year now. But since last week I've been having trouble connecting to the internet via mobile network. I have full signal, but no data connection.
At first the issue was intermittent, but now it's constant. Incidentally, sometime after I started getting problems (but during a brief period of time when I did in fact had a data connection) the device got upgraded to Android 4.4.4. Maybe the upgrade had something to do with the issue, but i'm sure that it started happening before the upgrade.
For some time I was sure that the issue was with the network. After long useless conversations with them I finally tried the sim on another device, and to my disappointment, it worked fine.
I also found out that if i change the preferred network mode to 2G, then i do get a data connection. That's not very useful.
Any thoughts?
I've been having a similar problem since the 4.4.4 update. I work in an LTE coverage area, and live in a 2G area. It transitions just fine from 2G into 3G and LTE, but then when I go back into the 2G area it drops signal entirely. Toggling airplane mode won't make it recover, but a full reboot will. After the reboot it works fine again. I'm considering trying a factory reset to see if that helps.

It seems random when the data connection works and the internet works on my phone. I'll sit there with full 3G signal and i get "cannot find the DNS Server" error when trying to load webpages :S
is this a problem with my Samsung Omnia 7, Windows Phone 7 or my network (Orange UK)?
I have this problem on my HD7 as well. If I have a 3G connection, it doesn't work. It only works on H (HSDPA).
Funnily enough, I had the same issue with my HD2 running WM6.5, which makes me wonder if WP7 is using the same comms drivers.
I have this problem too! A LOT everyday in diferent locations.
Actually how can I enable the HSDPA on my HD7? Because I can only get 3G.
These are just network errors.
I use internet alot and it happens on every device I had.
My WP7 is actually pretty stable in this regard.
Same! Never works on 3g only ever H you sure its just network errors cause it happens alot
YES this is a major problem for me with my Omnia 7, I even got a replacement phone from my carrier (Optus Australia) because of it... and it's exactly the same. It's extremely frustrating and makes the phone damn near unusable. Happens on every device? what a load of rubbish, if I put the SIM in my old iPhone 3GS it works FLAWLESSLY. I don't know what I'm going to do.

Can you explain then, how come a reboot always fixes the problem?

Yep, I have the same problem with my Omnia 7.
On all 3 of the networks i've used it on, T-Mobile, Virgin and GiffGaff.
Only solution is to reboot the phone.
I thing i've noticed, is it seems to happen when I move from an area where I have WiFi access (Home/Work/Cafe) to an area where i'm using a Phone network ?
I think we can only hope that the upcoming WP7 update fixes this. Also it seems enabling airplane mode then disabling it also fixes it in a similar way to rebooting the phone.

I'll make a note of that, cheers!
Im having the same issue with my HD7. Only EVER works on H. Not on G or 3G. It's driving me insane. The exact same sim on the same provider never had an issue on my Touch Pro 2, but this phone is shocking for internet
I get this occasionally on my HD7. Not really an issue right now. It does get annoying sometimes when the wifi in my house isnt strong enough to connect

You do realize that phones switch to H only while they are actively swapping data, then fall back to 3G while dormant, to save battery?
Try it - leave your phone alone for a bit and it will switch from H to 3G. Now access something on the net and it will switch to H (if possible) to get the data, then after a few seconds of inaction it will switch back to 3G.
So yes, it is correct that it only ever works on H!
Mind you, it would be nice if it worked on G too, I'm sure it should but mine never does.
hm i thought the " H " means that i dont get 3G signal.
but i think i had the same problem!
solution:
you only need to turn OFF WIFI
somehow its not using 3G when wifi networks are close,
even if you not connected to one.
turn OFF wifi or maybe only "discover new networks"
turning OFF wifi always brings me 3G back ...
Just to add my experience here...
I have a Samsung Omnia 7 and had never experienced any issues with 3G/H data/internet issues on the 3 network in the UK.
However, I've come over to Australia to visit the folks and have put in a Virgin SIM, now I really struggle with this. The connection just isn't working even with full 3G signal.
As pointed out, toggling my Airplane Mode works most of the time - I guess this is because the phone re-registers itself with the network when you enable>disable airplane mode (just like it would if you rebooted it). Curiously toggling the data connection option seems to have no effect.
Pain in the a*se.
I had connectivity issues with my Samsung Omnia 7. I worked out that my phone was not playing nice with my router and so my wifi connected but didn't actually work.
Also, I found that 3G performance was sub-par and many apps timed out because they were taking so long to get connection.
I solved these problems by flashing a new firmware. It was a little tricky and it is potentially risky, but a quick google will lead you to the relevant information.
I used a European firmware (I am in Australia on Optus), but it works fine. I just had to change all the language settings.
Now my phone's 3G and WiFi connections both work a lot faster (no more waiting for an eternity for the marketplace to open for example).
I have the same problem and read on create.msdn.com it has something to do with how wp7 handles the connections.
If the provider cuts off the connection frequently it loses its 3g signal or something like that. Thats why my push notifications are just unreliable. If I take my sim out and use wifi only. It just works and keeps working as soon as I connect to wifi. When 3g comes into play and the carrier cuts me off because im not actively using, the phone struggles to recconect for push etc.
Good evening all! Today I restarted my phone for the first time in a week and a half or so, and upon booting up it refused to connect to the mobile network. It says full service 4G, but the bars are gray and therefore no data connection can be established. I restarted my phone once more and then even pulled the battery and sim card and started it up. Nothing has worked. I got home and connected to WiFi just fine, but when I turn off WiFi I go back to no data connection.
Is anyone else using a CDMA Nexus and having a problem? I live in Cleveland, if it's a possible area issue. I haven't called yet, but I have searched all over the internet to no avail.
Currently running stock, rooted, 4.0.4. No other modifications.
No problems here, but I'm a good ways away from you.
well I'm finally able to connect to the network again (the signal bars are blue), but I'm still getting virtually no data connection. It works in sprints of a few seconds, but then doesn't work again for a minute or 2. There's either a problem with my phone or the network...but I'd lean toward the network since it works at times, but not others.
I live in Parma and have noticed spotier service then normal. Hopefully its temporary. Hasn't been too bad. Able to get 4g most of the time.
Sent from CDMA V6 SC GNexus w/Liquid & Franco.kernel
Installed the update this morning, and now I've totally lost data connection twice today. Shows 4 bars of LTE, but won't connect. Switching airplane mode on/off fixes it instantly.
This hasn't happened before (had it about 6 weeks), so I'm guessing this is a new bug.
I'd bet heavier on T-mobile doing work on towers in your area. They're doing this quite often these days. And I was seeing this behavior long before the update. May be no way to know for sure.
I was originally a Verizon user so I'm not used to this kind of weak connection.
I had my phone replaced already due to another issue a few weeks ago
so I don't want to get another replacement because of this. it is really annoying!
Instead I will ask here and see if anyone could help !
**This has nothing to do with WiFi (because WiFi works great!)**
**And nothing to do with calls because call quality and connection showed no problems**
**Not exactly sure this problem started, just started getting annoyed with it recently**
\- What my phone is doing (when I'm at home) -/
1. Slow transition from WiFi connection
- When I turn Wifi off, I don't get an immediate data reception. Instead it takes about 10 seconds and then I barely start to get 3g..... not lte .... (It's not like this in every place)
2. Not much LTE
- It happens really rarely, most of the time at home the connection is on 3g
3. Lose data connection even while in use
- It's just sometimes unstable. When I'm browsing the web (while in 3g) it would sometimes go down to no bars at all and lose internet connectivity, then the 3g and I have to wait again until it comes back.
- Data roaming automatically turns on saying that I lost connection -_-
4. 3g is sometimes really unresponsive
- Just like when it is when turning off Wifi
- 3g would stay idle for sometime, even when I open apps that require internet
- Sometimes the 3g just disappears and decides not to comeback for a while
5. Bars up and down (drains battery?)
- I see this too often, like in every hour. While in 3g, the bars get suddenly full, then in an instant it drops to 1, then to 2. Then sometimes to no bars at all.
* in LTE it never gets like this, just constantly 1 bar
6. Maybe it's where I live?
- Possibly, but it's quite an urban and Sprint should have no problem covering this area in my opinion
- Verizon wasn't like this (although not perfect)
7. This is annoying
-Because it is draining the battery -_-
-Because my sister's iPhone 6 performs better (always has 2~3 bars) & my brother's S6 (though relatively weaker than her's) does not seem to lose connection compared mine at home (We're all Sprint users)
\- What I've done to confront this problem -/
1) Called Sprint, but didn't help at all. They told me to just take it to the store and have them take a look -__- Agent hardly knew anything...
2) Flashed Stock ROM and hard reset the phone (so annoying since you have to set things up again)
3) Made sure I set mobile data Network Mode to 'AUTOMATIC'
4) Made sure I have the latest Software version and have the PRL and Profile updated
But still no result at this point.
***Could this be a hardware issue? Or a software issue that is fixable?***
Can anyone give me some advice on how to fix this?
I mean it's just that the data reception is too weak an unreliable to think this is okay.
Right now my phone is pretty empty, barely any apps because of the reset.
I really don't want to believe it's due to a faulty hardware!
P.S. Possibly symptom?
The first day I got this phone as a replacement out of the store, I was unable to connect to the internet using data, even though calling was working.
What it was doing was, constantly switching from 3g - lte - inactive 3g - nothing - 3g - so on in a 20 second cycle.
By the end of that day towards midnight it was connecting to the internet.
Welcome to Sprint -_____- my GF has 4G LTE on Verizon where I live and I don't even have 3G, I roam on Verizon actually lol. Sprint literally has ZERO coverage while Verizon has LTE.. It's just Sprint dude lol.
Hello,
I live in an area (like many of us) there T-mobile service isn't that great. I daily drive through areas with zero service and I have almost no service at my house so we utilize WIFI Calling.
I have been finding for the past few months that when I return to an area of good service (phone showing full bars of 4G or 4G LTE) that I cannot move any cellular data. If I reboot the phone then everything works again for a while. I have tried to toggle into airplane mode and back but this does not help, only a full reboot helps.
Does anyone else get this? Its very annoying to have to reboot the phone when I need to use cellular data. Appreciate some input. Phone is NOT rooted and running the latest available software from T-mobile

It happens all the time for me. I've not been able to figure out why it happens, but I've seen some speculation in other threads where people think it can break when switching between H+, 4G, LTE, etc. Some people have reported that switching to airplane mode and back fixes it, but it doesn't work for me. Only a reboot will fix it for me.
Here is another thread with some discussion on it:
http://forum.xda-developers.com/galaxy-s6-edge/help/mobile-network-data-connection-drops-t3097605
Thanks for the response. I'm not happy to hear it appears to be happening to everyone. I wonder if any of the carriers have reported this to Samsung?
I cleared the cache partition on my phone 2 days ago and I've been good since...that doesn't mean it fixed it but its been a while since I had 2 good days!
THIS HAPPENS TO ME OMG!!! I thought I was going crazy... it happens quite often in NYC where we travel by subway underground... Switching to Airplane mode then back indeed fix it majority of the time, but it doesn't work sometimes...
Also, this happens when i am on Wifi for extended period of time, and then leave WiFi, the phone will show 4G LTE but wont' push any data.
Going into Phone status will show that you have no IP Address...
edit: btw, i've done an exchange with Tmobile, and still happens on the phone, Swapped SIM card as well, doesn't solve the problem. T-Mobile ran diagnosis, and found nothing wrong. I suspect it might be T-Mobile's network configuration...
Also, I can almost 100% reproduce this when I am playing a game that requires periodic connection (like loading acount info), and then playing in the subway while doing data connection between subway station (we have internet at the station, but not in the tunnel) will break my 4G LTE data connection...
